The graph shows the growth curves for three independent populations (A, B, and C). The growth model for each of these populations is
N(t) = N0ert
where N(t) is the population at time t, No is the initial population and r is the per capita growth rate.
If rA, rB, rC are the intrinsic growth rates of populations A, B, and C respectively, which of these statements is true?
1
rA = rB = rC
2
rA > rB = rC
3
rA = rB > rC
4
rA > rB > rC
